Retinoblastoma

Retinoblastoma, an uncommon type of eye cancer, usually affects newborns and young children under the age of five. Retinoblastoma can develop spontaneously (non-heritable) or inheritively (heritable), impacting either one or both eyes. Many times, the heritable variant is associated with an RB1 gene mutation. 
Often seen in images, a white reflection in the pupil is one of the most typical indicators of retinoblastoma—also known as "cat's eye reflex" or leukocoria. Diagnosis calls for an extensive eye examination under anaesthesia, imaging tests including ultrasonic, MRI, or CT scans, and genetic testing should a hereditary cause be detected. Retaining vision and life depends on early detection.
In severe circumstances, they might call for chemotherapy, laser therapy, cryotherapy, radiation, or surgical removal of the eye (enucleation). Retinoblastoma has a really high survival rate with timely management; many children go on to lead normal, healthy lives.
